In an apparatus for sinking into the ground structure-supporting members comprising a base 3 having a downwardly directed cutting edge 4, a water extracting bore 3a, a hollow space 7 on its underside and holes 13 communicating with the upper and under sides, an extraction duct 6 provides communication between base bore and) a tank 8 above the ground and a pump 5 is connected with the duct to suck water and material from the space beneath the base. When the base resits on the ground the water beneath the base is extracted and waiter and/or returned water can pass from above through the holes in the base to give a jetting action so that the ground beneath the base will be softened and entrained with the extracted water. Figs. 8, 9, 10 (not shown) indicates the jetting and suction arrangements which may be used for a base split into three sections.

Title: Improvements in spark discharge ignition systems
Inventor: VEZIS ULDIS ADOLF
IPC: F02P3/08
Filed: 1956-10-24
Abstract: 832,992. Ignition systems. ELCONTROL Ltd. Oct. 23, 1957 [Oct. 24, 1996], No. 32391/56. Class 7(4) In an ignition system a main storage condenser, C 1  and/or C 2  adapted to be charged from a suitable voltage source and discharged through a spark gap G- for example of the surface discharge type -has normally open electromagnetically operated relay contacts A 1  in the discharge circuit thereof, and the operating coil A 2  of the relay is connected across the storage condenser through an electronic switch device (neon tube N) the break down potential of which is thereby derived from the the main condenser, whilst a breakdown control circuit associated with the switch determines the instant of breakdown thereof. As shown, the breakdown control circuit includes a time delay condenser C 3 . The contacts a 2  close at the same time as the contacts a 1  and discharge the condenser C 3 . The frequency of repetition of sparking is determined by the size of the time delay condenser C 3  and the values of the resistances R, and R 2 . Hence by varying the position of the tapping point P or the size of the time delay condenser C 3  the sparking frequency can be controlled. Other 'kinds of electronic switch than a neon tube or like glow discharge diode may be used such as a hard valve or a grid controlled gas discharge tube. In this case the timing condenser C a  may be replaced by some form of triggering circuit connected to the control grid. In this way a definite programme of discharges may be set up having no constant. repetition'frequency or a manual control may be arranged so that discharge occurs at will. If the electronic switch is a grid-controlled electron discharge tube the breakdown interval may in part be a function of the voltage time characteristic of the control grid circuit. This characteristic may be a step or ramp function the former being represented by say manual or time switch controlled contacts and the latter by say a constant speed potentiometer connected across a source of bias voltage. The gap G is optionally shunted by a resistance R 4 . The Specification refers to the application of the system to burner and furnace igniters where photo-electric flame failure protection is installed.

Title: Improvements in or relating to ammonia-methyl borate compounds
Inventor: SCHECHTER WILLIAM HOWARD
IPC: C07F5/00
Filed: 1952-12-23
Abstract: A method of making an addition compound of ammonia and trimethyl borate containing boron and nitrogen in 1 : 1 ratio comprises the steps of saturating with dry gaseous ammonia a mixture of trimethyl borate and methyl alcohol, recovering the crystalline reaction product, mixing said product with an alkali metal and/or an alkaline earth metal, and/or an hydride thereof and subliming the pure addition compound from the latter mixture. Pure methyl borate may be saturated with dry ammonia gas at room temperature and pressure.  The product has the formula NH3.B(OCH3)3.

Excess dry, gaseous ammonia and trimethyl borate vapour carried in nitrogen may be passed through a reaction tube and the product cooled to freeze out the desired addition compound.  The products may be used as fluxes in gas welding (see Group II).ALSO:Addition compounds obtained by reacting ammonia and trimethyl borate and which may contain bound methanol, represented, e.g., by the formul NH3.B(OCH3)3 or NH3.B(OCH3)3.

Abstract: 256,119. Longmore, S. Dec. 31, 1925. Locking nuts.-In a nut lock of the kind in which recesses in the nut and bolt are brought into register to form a cavity for a ball which is trapped when the nut is slackened, the recesses are of equal cross-sectional area and of equal depth throughout, the recess in the bolt or in both extends wholly or partly in a circumferential direction, and the recesses move out of register with one another at the surface of the nut when the ball is locked. The ball is dislodged by slightly tightening the nut. In the construction shown in Fig. 1, the nut has a number of longitudinal recesses 4 extending for the full depth of the nut and the bolt recess has a longitudinal portion 5 and a spiral portion 2. The portion 2 may be circumferential and the bolt slot may be wholly spiral in which case the nut slot extends for a part of the depth of the nut.

Abstract: 673,028. Smallarms. SCHWEIZERISCHE INDUSTRIE-GES. Dec. 23, 1949. [Dec. 23, 1948] No. 33025/49. Class 119. Automatic smallarms of the short-recoil type have the barrel moved laterally to unlock it from the breech block by engagement means, such as a pin and slot, designed to give initial axial sliding movement of the barrel before the unlocking movement occurs. In the form shown, the forwardly-extending breech block 1 is locked to the barrel 7 by interengaging teeth 12, the breech block being slidable in axial guides on the fixed casing or hand-grip 2, and the barrel being guided and actuated for unlocking by a fixed pin 10 engaging a shaped slot 9 on the barrel. During short recoil, the straight part of the slot ensures axial sliding movement of the barrel until the bullet has left the barrel, after which the cam-shaped end of the slot lowers the barrel to the unlocked position. The breech block then moves rearwardly alone against the action of the return spring 11 to permit of loading a cartridge P from a box magazine 16. On breech closure, the returning breech block feeds a cartridge forwardly from the magazine, the bullet engaging a guide 14 on the barrel to guide the cartridge into the gun chamber. The barrel is then pushed forwardly and upwardly to lock with the breech closure in firing position. In a modification, the pin 10 is fixed to the barrel and engages a shaped slot in the fixed casing.

Abstract: ClO2 and Cl2 are produced by continuously adding an alkali metal chlorate and chloride and a strong acid to a reaction vessel, maintaining a partial pressure of water such as to ensure crystallization of the alkali metal salt of the acid within the vessel, and continuously withdrawing the product gases and solid. The acid may be H2SO4 or H5PO4 and the alkali metal may be Na, K or Li. The chlorate and chloride may be added dry or as solution, separately or together, in a ratio of 1 : 1 to 1 : 6 respectively. H2SO4 used may be above 100%.
